Your Sensitive 20 Megapixel Microscope Camera forDemanding, True Color Imaging of Large Fields of View
The ZEISS Axiocam 820 color wasdesigned as the most flexible solution
for complex experiments anddemanding applications. Its squaresensor utilizes the optical field of viewof the microscope most efficiently
without compromising resolution
or speed. The 28 frames per second
full resolution speed allows imaging
processes without losing resolution
at all magnifications. For imaging
the fastest processes, the acquisition
speed can be further improved bybinning pixels or by using a sub-arrayof the sensor. Distortion-free image
acquisition is guaranteed because of theglobal shutter architecture.

The excellent dynamic range of thecamera can be improved further byusing the exclusive high dynamic range(HDR) mode for imaging both thedimmest and brightest details in one
image.
